Step one to most electric longboard builds is typically the acquisition of a foot operated longboard, with step two being the purchase of a ready-made motor bracket to electro-convert the strenuous vehicle. Not so [Matt Carl’s] scratch-built electric longboard, which starts out with four 1/8″sheets of baltic birch.
After copying his paper template to the wood, [Matt] applies wood glue to the sheets and squeezes them tightly together in a custom, concave press mould, where they are left to dry under heavy weight plates. After drying, the curved laminate is cut out with a jigsaw, sanded and painted.
For adequate propulsion, [Matt] designed a custom 3D printable mount to attach a beefy brushless motor to one of the trucks. His open source design also includes a pulley that attaches to one of the wheels, an enclosure for the electronics and a number of brackets to mount it all to the underside of the board. Besides wood and plastic, the bill of materials also includes a brushless motor, drive belt and motor pulley, two large LiPo packs, an ESC, RC transmitter and receiver, and an onboard charger.
The assembled result of [Matt’s] woodworking, CAD and 3D printing efforts is a slick and very capable electric longboard with a top speed of 20 mph and a range of 10 miles. Not bad for a mere $400 budget! Worried about the longevity of the 3D printed parts? Carbon-fiber-reinforced 3D printing filament has you covered. Check out the video below, where [Matt] walks you through the 3D-printed part of his build!
